OVM仿真出现的一些问题

jerome555

请教一下达人，以下是我在OVM环境下仿真的问题：
OVM_WARNING @ 0: reporter [BDTYP] Cannot create a component of type 'run_dma_basic' because it is not registered with the factory.
OVM_FATAL @ 0: reporter [INVTST] Requested test from command line +OVM_TESTNAME=run_dma_basic) not found.

请问有没有人知道，这个问题怎么解决？谢谢！
